전기집진기의 포집부 전극필림{ELECTRODE FILMS FOR A ELECTRIC DUST COLLECTOR}Electrode film collecting part of electrostatic precipitator {ELECTRODE FILMS FOR A ELECTRIC DUST COLLECTOR}

본 고안은 전기집진기에 관한 것으로, 특히 집진필터의 포집부 전극필림에 관한 것이다.The present invention relates to an electrostatic precipitator, and more particularly, to a collecting electrode film of the dust collecting filter.

전기집진은 전극사이에 고전계를 인가하여 공기중에 자유전자를 발생시키어 자유전자가 인가되는 고전계에 의하여 양극으로 가속되다가 다른 중성입자와 충돌하여 그 입자를 대전시키는 전계하전방식이 있다. 한편 유입되는 분진을 이온화시키는 부분을 전리부라 하고, 전리부는 방전극과 방전대응극으로 이루어지고, 이온화된 입자를 쿨롱힘에 의하여 전극에 부착시키는 부분을 포집부라 하고, 포집부는 포집전극(접지전극)과 포집대응극으로 이루어진다.Electrostatic precipitating is an electric field charging method in which a high electric field is applied between electrodes to generate free electrons in air, and the free electrons are accelerated to an anode by a high electric field to which free electrons are applied and then collide with other neutral particles to charge the particles. On the other hand, the ionizing part that ionizes the incoming dust is called an ionizing part, the ionizing part is composed of a discharge electrode and a discharge counter electrode, and a part which attaches ionized particles to the electrode by Coulomb force is called a collecting part, and the collecting part is a collecting electrode (ground electrode). And collection countermeasures.

종래 전기집진기는, 도 1 및 도 2에 도시된 바와 같이, 전리부케이스(1a)내에 방전대응극(2a)이 소정간격으로 설치되고, 상기 전리부케이스의 일측의 절연판(21)상에 지지대(22)가 설치되어 스프링(23)의 일단이 연결되며, 스프링(23)의 타단에는 방전선(24)이 연결되어 상기 방전대응극사이의 중앙에 위치하도록 설치되어 상기 방전선으로의 고전압 인가는 전리부케이스, 절연판, 지지대를 통하여 인가된다.In the conventional electrostatic precipitator, as shown in FIGS. 1 and 2, a discharge counter electrode 2a is installed in the ionizing unit case 1a at predetermined intervals, and a support stand is provided on the insulating plate 21 on one side of the ionizing unit case. 22 is installed so that one end of the spring 23 is connected, and the other end of the spring 23 is connected to the discharge line 24 so as to be positioned in the center between the discharge counter electrodes to apply a high voltage to the discharge line. Is applied through the ionizing case, insulation plate and support.

또한, 전리부와결합되는 포집부케이스(8a)내에는 순차적으로 절연성이 양호한 포집전극판(16c)과 가속전극판(18c)이 삽입되며 포집전극판과 가속전극판의 각각의 외주연에는 간격을 유지하는 돌기(15b)가 형성되고, 각각의 중앙부에는 알루미늄박지등으로 도전층을 형성하여 극판이 형성된다.In addition, a collecting electrode plate 16c and an acceleration electrode plate 18c having good insulation are sequentially inserted into the collecting part case 8a coupled to the ionizing part, and spaced at each outer circumference of the collecting electrode plate and the accelerating electrode plate. The projections 15b are formed, and the conductive plates are formed in each center portion of the aluminum foil or the like to form a pole plate.

포집부케이스의 상부양측에는 포집전극판인가단자(27)와 가속전극판인가단자(10a)가 설치되어 상기 포집전극판인가단자는 전리부의 방전선과 접지되고, 상기 가속전극판인가단자는 방전선과 동일전극의 전압이 인가되도록 구성된다.A collecting electrode plate applying terminal 27 and an acceleration electrode plate applying terminal 10a are installed on both sides of the collecting unit case, and the collecting electrode plate applying terminal is grounded with the discharge line of the ionizing unit, and the acceleration electrode plate applying terminal is connected to the discharge line. The voltage of the same electrode is configured to be applied.

전리부의 전리부케이스에 설치된 지지대를 통하여 방전선에 고전압이 인가되면, 방전대응극과의 사이에 코로나 방전이 발생되어 이 사이를 통과하는 먼지는 하전을 갖고 전리된다. 전리부에서 하전된 먼지가 포집부케이스내부를 통과하면, 포집전극판(16c)과 가속전극판(18c)사이의 전계강도에 의해 상기 포집전극판(16c)의 도전층에 쿨롱힘의 작용으로 먼지가 포집되고, 상기 가속전극판(18c)의 도전층에도 일부 먼지가 포집된다.When a high voltage is applied to the discharge line through the support provided in the ionizing part case of the ionizing portion, corona discharge is generated between the discharge counter and the dust passing through the ion is charged and ionized. When the dust charged in the ionizing portion passes inside the collecting case, the electric field strength between the collecting electrode plate 16c and the accelerating electrode plate 18c causes the action of the coulomb force on the conductive layer of the collecting electrode plate 16c. Dust is collected, and some dust is also collected in the conductive layer of the acceleration electrode plate 18c.

그러나, 전기집진기를 일정시간 사용하면 먼지가 포집되고, 포집전극판(16c)과 가속전극판(18c)사이의 간격이 밀접되어 있으므로 포집전극판(16c)과 가속전극판(18c)상에 포집된 먼지로 인해 절연파괴가 발생하여 분진포집이 원활하게 이루어지지 않는 문제점이 있다.However, when the electrostatic precipitator is used for a predetermined time, dust is collected, and the gap between the collecting electrode plate 16c and the acceleration electrode plate 18c is close, and thus the collection is performed on the collecting electrode plate 16c and the acceleration electrode plate 18c. There is a problem that dust collection is not made smoothly due to the breakdown caused by the dust.

본 고안은 이러한 종래기술의 문제점을 해결하기 위한 것으로, 포집된 먼지로 인한 절연파괴를 발생하지 않고 분진포집효율을 향상시킬 수 있는 전기집진기의 전극필림의 제공을 목적으로 한다.The present invention is to solve the problems of the prior art, it is an object of the present invention to provide an electrode film of the electrostatic precipitator which can improve the dust collection efficiency without causing an insulation breakdown due to the collected dust.

상기 목적을 달성하기 위하여, 본 고안의 전기집진기의 전극필림은, 포집부케이스에 장착된 필터지지판에 상호 순차적으로 스크롤형으로 감겨져 전극을 형성하는 포집전극필림과 가속전극필림를 갖는 전기집진기에 있어서, 가속전극필림은 내부에 도체가 수지로 인서팅압출되고 한편 공기흐름통로를 형성하도록 그 양단부의 상, 하면에 지그재그형태로 돌출된 돌기부가 형성된 것을 특징으로 한다.In order to achieve the above object, the electrode film of the electrostatic precipitator of the present invention, in the electrostatic precipitator having a collecting electrode film and an acceleration electrode film are wound in a scroll type sequentially on the filter support plate mounted on the collecting unit case to form an electrode, Accelerated electrode film is characterized in that the conductor is inserted into the resin extrusion extruded on the other hand, the projections protruding in a zigzag form on the upper and lower ends of the both ends to form an air flow passage.

이하, 본 고안의 전기집진기를 첨부도면에 의거하여 상세히 설명한다.Hereinafter, the electrostatic precipitator of the present invention will be described in detail with reference to the accompanying drawings.

본 고안의 전기집진기는, 도 3 내지 도 5에 도시된 바와 같이, 전리부는 전리부케이스(1)와 일체로 방전대응극(2)이 소정 간격으로 형성되고, 상기 전리부케이스의 상부일측에는 침방전극인가단자(3)가 설치되며, 상기 전리부케이스의 후방에는 침방전극(6)이 방전대응극사이의 중앙에 위치하도록 설치되며, 상기 전리부케이스와 침방전극사이에는 절연애자(7)가 설치된다.The electrostatic precipitator of the present invention, as shown in Figures 3 to 5, the ionizing portion is formed integrally with the ionizing portion case (1) discharge counter electrode 2 at a predetermined interval, the upper side of the ionizing portion case A needle electrode applying terminal 3 is provided, and a needle electrode 6 is installed at the rear of the ionizing part case so as to be located at the center between the discharge counter electrodes, and an insulator 7 between the ionizing part case and the needle electrode. Is installed.

또한 포집부는 포집부케이스(8)의 일측에는 가속전극필림 인가단자(10)가 설치되고, 포집부케이스의 내부에는 금속망(12)이 설치된다.In addition, the collecting unit case is provided with an acceleration electrode film applying terminal 10 on one side of the collecting unit case 8, the metal mesh 12 is installed inside the collecting unit case.

포집부케이스의 후방에 장착되는 필터지지판(13)에는, 알루미늄재질의 포집전극필림(16)과 내부에 박판의 도체(17)가 졀연성 수지물로 인서팅 압출된 가속전극필림(18)의 각각의 일단이 상호 순차적으로 스크롤형으로 감겨서 전극을 형성한다.In the filter support plate 13 mounted on the rear of the collecting part case, the collecting electrode film 16 made of aluminum and the conductive electrode 17 of the thin plate therein are inserted and extruded into a flexible resin material. Each end is sequentially scrolled with each other to form an electrode.

상기 가속전극판(18)의 수지물의 양단의 상하면에는, 도 6 및 도 7에 도시된 바와 같이, 공기흐름통로를 위해 지그재그형태로 간격을 유지하는 돌기부(15)가 형성되어 있다.On the upper and lower surfaces of both ends of the resin material of the acceleration electrode plate 18, as shown in Figs. 6 and 7, the protrusions 15 are spaced in a zigzag form for the air flow passage.

또한, 포집전극필림(16)은, 포집부케이스(8)에 접지되고, 가속전극필림(18)은 상기 포집부케이스와 필터지지판사이에 절연을 유지하는 절연애자(7)에 고정되어, 다시 가속전극필림인가단자(10)을 통해 고전압이 인가된다.In addition, the collecting electrode film 16 is grounded to the collecting part case 8, and the acceleration electrode film 18 is fixed to the insulator 7 which maintains the insulation between the collecting part case and the filter support plate, and again. The high voltage is applied through the acceleration electrode film applying terminal (10).

전리부케이스(1) 상부의 침방전극 인가단자(3)을 통해 고전압을 인가하게 되면, 상기 전리부케이스와 일체로 형성된 방전대응극(2)과 침방전극(6)사이에 방전전류가 흐르면서 통과되는 먼지를 하전시킨다. 이때, 침방전극(6)은 통과되는 먼지에 대한 침단에서의 국부적인 강한 하전능력을 발휘하여 먼지의 이온화율을 증대시키며, 상기 침방전극에서의 방전시 발생되는 방전전류는 상기 포집부케이스(8)내에 설치된 금속망(12)과도 방전하여 방전전류를 증대시키어 먼지의 하전능력을 향상시키게 된다. 이때, 포집부케이스의 후방에 장착된 필터지지판(13)에 각각의 일단이 상호 순차적으로 스크롤형으로 감겨서 전극이 형성된 포집전극필림(16)은 포집부케이스에 접지되고, 가속전극필림(18)이 절연애자를 통하여 절연을 유지하면서 포집부케이스의 일측에 설치된 가속전극필림인가단자(10)를 통해 고전압이 인가되면, 포집전극필림(16)과 가속전극필림(18)사이에 전계가 형성되어 하전된 먼지가 통과하면서 먼지가 포집전극필림(16)에 포집된다.When a high voltage is applied through the needle electrode applying terminal 3 on the upper portion of the ionizing unit case 1, a discharge current flows between the discharge counter electrode 2 and the needle electrode 6 formed integrally with the ionizing unit case. Charge the dust. At this time, the needle electrode 6 exerts a local strong charging capacity at the stepping on the dust passing through to increase the ionization rate of the dust, the discharge current generated during the discharge on the needle electrode is the collection case (8) Also discharged with the metal net 12 installed in the) to increase the discharge current to improve the charge capacity of the dust. At this time, the collecting electrode film 16, in which one end of each of the ends of the filter support plate 13 mounted to the rear of the collecting unit case is sequentially scrolled to each other, is grounded to the collecting unit case, and the acceleration electrode film 18 is formed. When a high voltage is applied through the acceleration electrode film applying terminal 10 installed at one side of the collecting part case while maintaining insulation through the insulator, an electric field is formed between the collecting electrode film 16 and the acceleration electrode film 18. As the charged dust passes, the dust is collected in the collecting electrode film 16.

이때, 가속전극필림(18)이 절연성 수지물의 내부에 박판의 도체(17)가 인서팅압출되어 있으므로 상기 도체(17)가 노출되지 않아 포집전극필림(16)과 가속전극필림(18)에 부착된 먼지로 인하여 포집전극필림(16)과 가속전극필림(18)사이에 절연파괴가 발생되는 것을 방지하게 된다.At this time, since the accelerated electrode film 18 is inserted and extruded into a thin sheet of conductor 17 inside the insulating resin material, the conductor 17 is not exposed and thus is attached to the collecting electrode film 16 and the accelerated electrode film 18. Due to the dust, insulation breakdown is prevented between the collecting electrode film 16 and the accelerating electrode film 18.

한편, 상하면에 지그재그 형태로 간격을 유지하여 공기흐름통로를 형성하는 돌기부(15)가 형성된 가속전극필림(18)과 포집전극필림(16)을 상호 순차적으로 스크롤형으로 감겨서 전극을 형성하므로, 포집면적이 확대되어 평판포집전극보다 뛰어난 포집성능을 발휘하여 분진 포집 효율을 향상시킬 수 있다.Meanwhile, since the acceleration electrode film 18 and the collecting electrode film 16 are sequentially scrolled to form electrodes by maintaining a gap in a zigzag shape to form an air flow path, the electrodes are formed by sequentially scrolling each other. As the collecting area is expanded, the collecting performance is superior to that of the flat plate collecting electrode, thereby improving the dust collecting efficiency.

이상, 설명한 바와 같이, 본 고안의 전기집진기에 따르면, 상하면에 지그재그 형태로 간격을 유지하여 공기흐름통로를 형성하는 돌기부가 형성된 가속전극필림과 포집전극필림을 상호 순차적으로 스크롤형으로 감아 전극을 형성하므로, 포집면적이 확대되어 평판포집전극보다 뛰어난 포집성능을 발휘하여 분진 포집 효율을 향상시킬 수 있다.As described above, according to the electrostatic precipitator of the present invention, an electrode is formed by sequentially scrolling an acceleration electrode film and a collecting electrode film each having a protrusion formed on the upper and lower surfaces thereof in a zigzag shape to form an air flow path. As a result, the collecting area is expanded, and thus, the collecting performance is superior to that of the flat plate collecting electrode, thereby improving the dust collecting efficiency.
